Are you working on rtems.git/master branch or /5 branch? Note that you
need to be sure to use a consistent compiler toolchain based on the
version of RTEMS that you use.

In rtems/5 branch we don't have waf support integrated yet. The
upgrade to waf is happening currently on the master branch, which will
eventually become the RTEMS version 6 release.

For GSoC students we expect development to happen on the development
head and not a release, so please make sure that you have the
toolchain built from rtems-source-builder.git/master and the rtems
source tree from rtems.git/master.

Currently, the waf-based build of rtems only supports "in tree"
builds, which means you need to run waf from within the rtems.git/
root of your source. This is a limitation of the waf build.

FWIW, waf build improvements could also fall under GSoC effort,
although no one has written it up as a task yet. It would be mostly

Sometimes the solutions only exist inside other people's heads, so
asking questions is encouraged.
